Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaics, in particular to a positioning device and a transmission device. Background Art

[0002] In the photovoltaic field, the thickness of battery cells is gradually decreasing, the production capacity of equipment is constantly increasing, and the quality requirements for battery cells are getting higher and higher. At present, the positioning methods of stringing machines include mechanical positioning or visual positioning + manipulator. In actual production, mechanical positioning uses double cylinder clamping, but due to the thinning of battery cells, the fragmentation rate continues to rise, the string return rate is too high, and at the same time, the thinning elasticity of battery cells increases, and the battery cells will still be displaced, resulting in subsequent poor production. For the method of visual positioning + manipulator handling, the positioning time becomes longer and the equipment cost is also increasing. In actual operation, the battery cell is positioned after the front PL detection. If there is a hidden crack in the battery cell, it can only be found after the subsequent stringing, causing the entire battery string to need to be repaired. The increase in the string return rate also causes a waste of time for repair. Utility Model Content

[0029] The embodiment of the present application provides a positioning device to solve the problems of cell splitting, high fragmentation rate and high string return rate when positioning cells in a string in the prior art. The positioning device will be described below in conjunction with the accompanying drawings.

[0030] The positioning device 100 provided in the embodiment of the present application is exemplified as shown in Figure 1, and Figure 2 is a schematic diagram of the structure of the positioning device 100 provided in the embodiment of the present application. The positioning device 100 of the present application can be used for photovoltaic module production.

[0031] In order to more clearly illustrate the structure of the positioning device 100, the positioning device 100 will be introduced below in conjunction with the accompanying drawings. For example, please refer to Figure 2, which is a schematic diagram of the structure of the positioning device 100 provided in an embodiment of the present application.

[0032] A positioning device 100 includes a first positioning mechanism 110 and a second positioning mechanism 120. The first positioning mechanism 110 includes a first positioning plate 111, an elastic component 112, and a first driving component 113. The second positioning mechanism 120 includes a second positioning plate 121 and a second driving component 122. The first positioning plate 111 and the second positioning plate 121 are arranged opposite to each other on both sides of a conveying component 200. The first driving component 113 is connected to the first positioning plate 111 through the elastic component 112. The second driving component 122 is connected to the second positioning plate 121. The first driving component 113 drives the first positioning plate 111 to move, and the second driving component 122 drives the second positioning plate 121 to move. The movement of the first positioning plate 111 cooperates with the second positioning plate 121 to realize the correction of the position of the battery cell 20 on the conveying component 200.

[0033] In the present application, the second driving component 122 drives the second positioning plate 121 to move to a predetermined position. The contact between the second positioning plate 121 and the battery cell 20 is hard contact. After the second positioning plate 121 moves to the predetermined position, it can limit one of the side edges of the battery cell 20. After the first positioning plate 111 contacts the other side edge of the battery cell 20 under the drive of the first driving component 113, under the action of the elastic component 112, flexible contact with the battery cell 20 is achieved. The elastic component 112 can slow down the impact of the second positioning plate 121 on the battery cell 20 and reduce the fragmentation rate.

[0034] In some of the embodiments, see FIG. 2, which is a partial structural diagram of a positioning device 100 according to an embodiment of the utility model, the first positioning mechanism 110 further includes a first positioning wheel 114. The first positioning wheel 114 is rotatably connected to the first positioning plate 111, and the rotation axis of the first positioning wheel 114 is perpendicular to the conveying surface of the conveying component 200. The present application achieves positioning of the battery cell 20 by arranging the first positioning wheel 114 on the first positioning plate 111, and by contacting the first positioning wheel 114 with one of the side edges of the battery cell 20. The arrangement of the first positioning wheel 114 can reduce the contact area between the first positioning mechanism 110 and the battery cell 20, reduce the hard impact on the battery cell 20, and reduce the fragmentation rate.

[0035] In some embodiments, as shown in FIG. 2 , there are multiple first positioning wheels 114. Multiple first positioning wheels 114 are arranged at intervals along the transmission direction. In FIG. 2 , two first positioning wheels 114 are shown. Driven by the first driving component 113, the two first positioning wheels 114 can synchronously contact one of the side edges of the battery cell 20. At the same time, due to the setting of the elastic component 112, the two first positioning wheels 114 are also flexibly contacted and positioned when contacting the battery cell 20.

[0036] In some embodiments, the first positioning wheel 114 is elastic. The elastic first positioning wheel 114 can reduce the impact force when it contacts the edge of the battery cell 20, has a certain buffering effect at the moment of contact, and reduces the fragmentation rate of the battery cell 20.

[0037] In some embodiments, the first positioning wheel 114 is a rubber wheel.

[0038] In some embodiments, as shown in FIG. 2 , the second positioning mechanism 120 further includes a second positioning wheel 123. The second positioning wheel 123 is rotatably connected to the second positioning plate 121, and the rotation axis of the second positioning wheel 123 is perpendicular to the conveying surface of the conveying component 200. The present application arranges the first positioning wheel 114 on the second positioning plate 121, and the second positioning wheel 123 contacts one of the side edges of the battery cell 20 to achieve positioning of the battery cell 20. The arrangement of the second positioning wheel 123 can reduce the contact area between the second positioning mechanism 120 and the battery cell 20, reduce the hard impact on the battery cell 20, and reduce the fragmentation rate.

[0039] In some embodiments, as shown in FIG. 2 , the number of the second positioning wheels 123 is multiple. The multiple second positioning wheels 123 are arranged at intervals along the transmission direction. Two second positioning wheels 123 are shown in FIG. 2 , and the two second positioning wheels 123 can synchronously contact the other side edge of the battery cell 20 under the drive of the first driving component 113. In the present application, since the second positioning mechanism 120 is not provided with an elastic component 112, the contact between the battery cell 20 and the second positioning mechanism 120 is a hard contact, and the second positioning wheel 123 on the second positioning mechanism 120 is used for limiting the position of one of the side edges of the battery cell 20. When the battery cell 20 contacts the multiple second positioning wheels 123, the position of the corresponding side edge of the battery cell 20 is limited and positioned. After positioning is completed, when the first driving component 113 is reset and the power is removed, the first positioning plate 111 and the first positioning wheel 114 will not be separated from the battery cell 20 immediately under the action of the elastic component 112, but will be separated from the battery cell 20 after the elastic restoring force of the elastic component 112 is released to zero. This arrangement can ensure that the position of the battery cell 20 will not change after positioning, and the positioned battery cell 20 will reach the position required for the next process.

[0040] In some embodiments, the second positioning wheel 123 is elastic. The elastic second positioning wheel 123 can reduce the impact force when it contacts the edge of the battery cell 20, has a certain buffering effect at the moment of contact, and reduces the fragmentation rate of the battery cell 20.

[0041] In some embodiments, the second positioning wheel 123 is a rubber wheel.

[0042] The present application realizes positioning of the battery cell 20 by setting a first positioning wheel 114 and a second positioning wheel 123. The setting of the first positioning wheel 114 and the second positioning wheel 123 further reduces the contact area between the positioning component and the battery cell 20, further reduces the impact on the battery cell 20 during the positioning process, and reduces the fragmentation rate.

[0043] An embodiment of the present application also provides a transmission device 10.

[0044] As shown in FIG. 1 , a transmission device 10 includes a transmission component 200 and a positioning device 100 . A first positioning plate 111 and a second positioning plate 121 of the positioning device 100 are respectively disposed on two sides of the transmission component 200 .

[0045] In some embodiments, the conveying member 200 may be a conveyor belt. There may be multiple conveyor belts, as shown in FIG. 1 , where multiple conveyor belts are arranged in parallel.

[0046] The above-mentioned positioning device 100, through the flexible tooling composed of the first positioning plate 111 and the elastic component 112, applies smaller force to the battery cell 20 during the positioning and correction process, ensuring that the force on the battery cell 20 during the positioning process is reduced, and can also be positioned more accurately. Compared with hard mechanical positioning, the flexible positioning of the present application is more accurate, reduces the fragmentation rate of the battery cell 20, and also reduces the downtime of the production equipment, reduces the string return rate of the battery cell 20, and has a low production cost of photovoltaic modules.

[0047] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0048] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
